Many of the world’s most famous brands — such as Burberry and Apple — simply raised their UK prices to try and make sure what they sold cost broadly the same across their international markets.

But luxury footwear brand Crockett & Jones, which has 12 stores worldwide across locations including London, Paris and New York as well as global wholesale partners, says it has deliberately left prices unchanged.

"The last thing we want to do is abuse our customer confidence and raise prices in the UK.” says James Fox, export sales director at the firm.

Mr. Fox believes that in the long term it’s best to keep pricing simple.

He says generally any discrepancies tend to average out across currencies, and that re-pricing is only possible "once or twice a year" due to the upheaval it causes for the business overall.

So is he concerned that the firm could be losing out financially?

"We are fortunate to be in a position that we have a few very strong ’Brexit proof’ markets which underpin the company when the UK is trying its best to screw up international trade," says Mr. Fox.

By selling both through its own stores and through wholesalers the firm’s risk is already spread out, he adds.

But it is also important not to be too greedy. Many US retailers that have come to the UK have simply swapped their dollar signs on their US price tags for pounds - betting that British consumers will be willing to pay a premium for their goods.

Yet for retailers doing a straight currency conversion from their local currency to the country where they are selling their goods also doesn’t necessarily work.

Many firms, particularly larger brands such as Hermes also use currency hedging to protect themselves. This involves working with a bank to buy currency at the current rate to protect themselves against adverse future volatility.

In the end, though Ms. Strachan says a company’s ability to cope with currency volatility comes down to how much people want to buy what they sell.
